Description

A smoke removal structure for moxibustion robots Technical Field

[0001] This utility model relates to the field of smoke removal technology for moxibustion, specifically to a smoke removal structure for a moxibustion robot. Background Technology

[0002] Moxibustion is a traditional Chinese medicine therapy that promotes blood circulation by burning moxa sticks to generate heat radiation. Due to its unique efficacy and low side effects, it is increasingly favored by modern people. With the popularization of smart devices in people's lives, moxibustion robots are gradually replacing manual moxibustion. In order to solve the problem of moxa smoke generated during the moxibustion process, moxibustion robots are generally equipped with a smoke removal system to filter and purify it to achieve the smoke removal effect. Most of these smoke removal systems use a negative pressure fan to draw the moxa smoke into the filter box inside the smoke removal box through the smoke pipe for filtration.

[0003] Currently, the smoke removal system of moxibustion robots typically fixes the negative pressure fan to the bottom surface of the casing via a flange, and then attaches the smoke pipe at the bottom of the smoke removal box to the connection port of the bottom plate inside the casing, so that the air inlet of the negative pressure fan is connected to the smoke removal box inside the casing through the connection port at the bottom of the casing.

[0004] However, because the flue pipe and the negative pressure fan are not directly connected, when the smoke removal box inside the casing needs to be disassembled for maintenance, the flue pipe will detach directly from the connecting port on the bottom of the casing. At this time, the air inlet of the negative pressure fan will be directly exposed at the connecting port of the casing, creating a gap between the flue pipe and the connecting port that cannot be sealed. During disassembly and maintenance, if the operator makes a mistake (such as a slipped screw or a loose nut), small parts may fall out during the disassembly process.

[0005] Because the existing bottom connection port of the casing only serves as an air passage and does not have any foreign object protection structure (such as mesh or baffle), it cannot prevent parts from falling during installation. As a result, the parts fall along the inner wall of the casing to the bottom connection port and eventually enter the air inlet of the negative pressure fan. When the negative pressure fan is running, the falling parts will collide with the internal fan impeller, resulting in problems such as impeller deformation and bearing wear. In severe cases, it may even damage the fan and affect its normal use in medical, health and wellness scenarios. Summary of the Invention

[0006] In view of this, the present invention provides a smoke removal structure for a moxibustion robot. By not connecting the negative pressure fan to the bottom plate of the casing, the negative pressure fan is directly connected to the smoke pipe, so that the air inlet of the negative pressure fan is directly sealed, thereby preventing parts that fall off during disassembly and assembly from entering the air inlet of the negative pressure fan, thus protecting the negative pressure fan.

[0007] To solve the above-mentioned technical problems, this utility model provides a smoke removal structure for a moxibustion robot, including a housing, a smoke removal box installed inside the housing, a smoke exhaust pipe welded to the bottom of the smoke removal box, and a connecting port on the bottom plate of the housing corresponding to the position of the smoke exhaust pipe. The lower end of the smoke exhaust pipe passes through the connecting port of the housing and connects to a negative pressure fan, thus decoupling the negative pressure fan from the bottom plate of the housing. This completely seals the air inlet of the negative pressure fan with the smoke exhaust pipe, preventing the air inlet of the negative pressure fan from being exposed at the connecting port of the housing. During disassembly and maintenance, parts that fall off will not enter the air inlet of the negative pressure fan but will fall directly onto the bottom plate of the housing, thereby protecting the negative pressure fan and preventing damage to it.

[0008] A discharge trough is provided at the connection port of the casing. The lower end of the exhaust pipe passes through the discharge trough and connects to the air inlet of the negative pressure fan. There is a gap between the discharge trough and the outer wall of the exhaust pipe, so that parts can fall out from the gap between the discharge trough and the exhaust pipe, making it convenient for workers to pick them up.

[0009] The discharge trough has a ring structure, which facilitates the passage of the exhaust pipe. Furthermore, the outer diameter of the discharge trough is larger than the outer diameter of the exhaust pipe, allowing parts to fall smoothly through the gap between the discharge trough and the exhaust pipe.

[0010] The exhaust pipe and the negative pressure fan are detachably connected via a flange. The bottom of the exhaust pipe is equipped with a flange, and the negative pressure fan is connected to the flange with bolts and nuts, thus connecting the negative pressure fan and the exhaust pipe together, which facilitates the disassembly, assembly and maintenance of the negative pressure fan by the staff.

[0011] The upper part of the smoke removal box is fitted with a sealing cover via a hinge. After the filter box is placed inside the smoke removal box, the sealing cover is flipped to seal the filter box. A connecting pipe is located on the upper part of the sealing cover. The operator connects the two ends of the corrugated hose to the smoke outlet of the equipment and the end of the connecting pipe, respectively. After the filter box is sealed, the negative pressure fan is started, allowing the smoke to be drawn into the filter box through the corrugated pipe and the connecting pipe, where it is filtered by the pre-filter cotton and other filter components.

[0012] The sealing cover is equipped with a spring clip. After the filter box is installed, the sealing cover is flipped over so that the inner bottom surface of the sealing cover fits tightly against the upper surface of the filter box, thereby sealing the filter box. Then, the spring clip is used to fix the sealing cover to the dust collector box to prevent the sealing cover from loosening and causing gaps between it and the filter box.

[0013] The smoke removal box has a one-sided opening design. By opening the side of the smoke removal box facing the door panel, the filter box can be slid out or put into the smoke removal box through the opening, making it easier for staff to take out the filter box and making it more convenient to replace the filter components inside the filter box.

[0014] The spring clip is located on the side of the sealing cover facing the opening of the smoke removal box, and the hinge on the sealing cover is located on the side away from the opening. A baffle is hinged below the opening of the smoke removal box, allowing the baffle to be flipped to the opening of the smoke removal box. The baffle can block and seal the filter box at the opening of the smoke removal box. The top of the baffle is connected and fixed to the sealing cover by the spring clip. Thus, while the sealing cover seals the filter box, the baffle can limit the filter box from the opening of the smoke removal box, making it more practical.

[0015] The casing has an internal frame for securing the equipment. The frame is used to secure various devices inside the casing. The smoke removal box is detachably mounted on the frame with bolts. By making through holes on the surfaces where the frame and the smoke removal box contact each other, bolts are passed through the through holes and then secured with nuts to fix the smoke removal box to the frame, which facilitates the assembly and disassembly of the smoke removal box.

[0016] The connecting pipe is detachably mounted on the top of the sealing cover via a threaded connection. The lower part of the connecting pipe has an external threaded surface. After the lower end of the connecting pipe is passed through the through hole of the sealing cover, a nut is threaded onto the external threaded surface of the connecting pipe to install and fix it. The detachable design of the connecting pipe makes it convenient for staff to disassemble and maintain it.

[0017] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0018] 1. When this utility model is used, the exhaust pipe is directly and seamlessly connected to the negative pressure fan, completely sealing the air inlet. This effectively prevents parts that fall off during disassembly and assembly from entering the fan, completely solving the problem of impeller damage caused by foreign objects getting stuck, significantly extending the service life of the negative pressure fan, and ensuring the safety of equipment operation.

[0019] 2. When this utility model is in use, the matching design of the gap between the annular discharge trough and the outer wall of the exhaust pipe allows accidentally dropped parts to fall directly onto the bottom plate of the machine casing along the gap, avoiding the accumulation and blockage of parts. At the same time, it facilitates quick positioning and recovery of parts, greatly improving maintenance efficiency.

[0020] 3. When in use, this utility model adopts a dual limiting structure of a side-opening smoke removal box, a flip-up sealing cover, and a spring-loaded buckle linkage baffle to achieve quick replacement and stable sealing of the filter box, simplify the filter component replacement process, and at the same time ensure the airtightness of the smoke removal system to avoid smoke leakage affecting the purification effect.

[0021] 4. When this utility model is used, the modular design (flange connection, detachable connecting pipe, bolt fixing frame) allows the negative pressure fan, smoke exhaust pipe and smoke removal box to support quick disassembly and assembly, reducing the difficulty of equipment maintenance, improving maintenance flexibility, and adapting to the efficient operation and maintenance needs of medical and healthcare scenarios.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to Figures 1-5. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0034] A smoke removal structure for a moxibustion robot, as shown in Figures 2, 3, and 4, includes a housing 100, a smoke removal box 200 installed inside the housing 100, and a filter box 205 installed inside the smoke removal box 200. The smoke removal box 200 and the filter box 205 are used to filter and remove the moxa smoke generated during moxibustion. A smoke exhaust pipe 201 is welded to the bottom of the smoke removal box 200. A connecting port is opened at the bottom plate of the housing 100 corresponding to the position of the smoke exhaust pipe 201. The lower end of the smoke exhaust pipe 201 passes through the connecting port of the housing 100 and connects to a negative pressure fan 300, so that the negative pressure fan 300 is no longer connected to the bottom plate of the housing 100. Furthermore, there is no gap between the exhaust pipe 201 and the negative pressure fan 300, which completely seals the air inlet of the negative pressure fan 300. This prevents the air inlet of the negative pressure fan 300 from being exposed at the connection point of the casing 100. As a result, when workers are disassembling or repairing the equipment inside the casing 100, the air inlet of the negative pressure fan 300 is sealed by the exhaust pipe 201, preventing fallen parts from entering the air inlet of the negative pressure fan 300. Instead, the parts fall directly onto the bottom plate of the casing 100, thus protecting the negative pressure fan 300 from damage.

[0035] Specifically, a discharge trough 101 is provided at the connection port of the housing 100. When the negative pressure fan 300 is installed, the lower end of the exhaust pipe 201 is passed through the discharge trough 101 and then connected to the air inlet of the negative pressure fan 300. There is a gap between the discharge trough 101 and the outer wall of the exhaust pipe 201, so that when a part falls, the part will fall through the gap between the discharge trough 101 and the exhaust pipe 201, making it convenient for the staff to pick it up.

[0036] Specifically, the discharge trough 101 has a ring structure. The ring structure of the discharge trough 101 facilitates the passage of the exhaust pipe 201, and the outer diameter of the discharge trough 101 is larger than the outer diameter of the exhaust pipe 201, so that the parts can fall smoothly from the gap between the discharge trough 101 and the exhaust pipe 201.

[0037] Furthermore, the exhaust pipe 201 and the negative pressure fan 300 are detachably connected via a flange. The bottom of the exhaust pipe 201 is equipped with a flange, and the negative pressure fan 300 has connecting shafts 301 on both sides for inserting bolts. The connecting shafts 301 have through holes. Workers use bolts to pass through the through holes of the connecting shafts 301 and the flange in sequence, and then connect the nuts to the bolts after they have been inserted, thereby connecting the negative pressure fan 300 and the exhaust pipe 201 together, which facilitates the disassembly, assembly and maintenance of the negative pressure fan 300.

[0038] As shown in Figures 1, 2, and 5, a sealing cover 202 is hinged to the upper part of the smoke removal box 200. After the filter box 205 is placed inside the smoke removal box 200, the filter box 205 is sealed by flipping the sealing cover 202. A connecting pipe 206 is provided on the upper part of the sealing cover 202. The end of the robotic arm 500 outside the housing 100 is used to install moxibustion. The operator connects one end of the corrugated hose to the smoke outlet 501 of the robotic arm 500, and then inserts the other end into the connecting pipe 206. After the sealing cover 202 seals the filter box 205, the negative pressure fan 300 is started. Since the filter box 205 is sealed by the sealing cover 202 inside the smoke removal box 200, the smoke from the moxibustion is drawn into the filter box 205 by the negative pressure fan 300 through the corrugated pipe and the connecting pipe 206. The smoke is then filtered by the primary filter cotton and other filter components inside the filter box 205, thereby completing the smoke removal and purification.

[0039] Specifically, the sealing cover 202 is equipped with a spring clip 204. The spring clip 204 is a common structure used to fix two separable items together. After the filter box 205 is installed, the sealing cover 202 is flipped over so that the inner bottom surface of the sealing cover 202 fits tightly against the upper surface of the filter box 205, thereby sealing the filter box 205. Then, the spring clip 204 fixes the sealing cover 202 to the dust collector box to prevent the sealing cover 202 from loosening and causing gaps between it and the filter box 205.

[0040] Specifically, the housing 100 has an openable door panel 102 on one side of its surface, and the smoke removal box 200 has a one-sided opening design. By opening the smoke removal box 200 on the side facing the door panel 102 of the housing 100, the filter box 205 can slide out or be placed into the smoke removal box 200 through the opening, making it easier for staff to take out the filter box 205 and making it more convenient to replace the filter elements in the filter box 205.

[0041] Furthermore, the connecting pipe 206 is detachably mounted on the top of the sealing cover 202 via a threaded connection. The lower part of the connecting pipe 206 has an external threaded surface, and the upper surface of the sealing cover 202 has a matching through hole. After the lower end of the connecting pipe 206 is passed through the through hole of the sealing cover 202, a nut is threaded onto the external threaded surface of the connecting pipe 206 to install the connecting pipe 206. The detachable nature of the connecting pipe 206 facilitates disassembly and maintenance by personnel.

[0042] As shown in Figure 5, the spring clip 204 is located on the side of the sealing cover 202 facing the opening of the smoke removal box 200, and the hinge on the sealing cover 202 is located on the side away from the opening. A baffle 203 is hinged below the opening of the smoke removal box 200, so that the baffle 203 can be flipped to the opening of the smoke removal box 200 by the hinge, so that the baffle 203 can block and seal the filter box 205 at the opening of the smoke removal box 200.

[0043] The spring clip 204 is usually divided into two parts, which can be interlocked. The two parts of the spring clip 204 are respectively set on the top of the baffle 203 and the side wall of the sealing cover 202 facing the opening. When the baffle 203 is flipped to the opening position of the smoke removal box 200, and the sealing cover 202 has been placed on the top of the filter box 205 for sealing, the top of the baffle 203 and the sealing cover 202 can be connected and fixed by the spring clip 204. Thus, while the sealing cover 202 seals the filter box 205, the baffle 203 can block the filter box 205 from the opening position of the smoke removal box 200 to limit the filter box 205. This allows the spring clip 204 to achieve a dual effect, making it more practical.

[0044] As shown in Figures 1, 3, and 4, a frame 400 for fixing equipment is provided inside the housing 100. The frame 400 is used to fix various devices inside the housing 100. The smoke removal box 200 is detachably installed on the frame 400 by bolts. By opening through holes at the contact points between the frame 400 and the smoke removal box 200, bolts are passed through the through holes and then fixed with nuts to fix the smoke removal box 200 on the frame 400, which facilitates the assembly and disassembly of the smoke removal box 200.

[0045] It is worth mentioning that, in order to make the smoke removal box 200 more stable, a support plate 401 can be welded to the frame 400 at a position that can contact the bottom surface of the smoke removal box 200. After the smoke removal box 200 is connected to the frame 400, the smoke removal box 200 can sit on the support plate 401, so that the support plate 401 supports the smoke removal box 200. Similarly, bolts can be used to connect the support plate 401 and the smoke removal box 200 together to further improve the stability of the smoke removal box 200.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
